Designation. Specific Plan zoning districts shall be delineated on the zoning map in a manner similar to that of any other zoning district except that each Specific Plan-zoned area shall also bear a name, number, symbol, or other delineation, as determined by the planning director, which distinguishes it from other Specific Plan zones, base zoning districts, or overlay zones. The assignment of the Specific Plan zone designation serves to provide a reference to the corresponding Specific Plan zoning document adopted by ordinance of the city council. Applicable zoning regulations and standards applicable to the land area are provided in the Specific Plan zones document, as adopted by reference in this title.
